After the press conference Superman realized how distant he'd become from the people he lived amongst on the planet, Kal decides to travel across America to find himself again.
Superman's first stop is Philadelphia and the media are following him every step of the way. Amongst the journalists and bewildered public is Clark Kent's wife Lois Lane. She asks Superman for his cover story at the Daily Planet, after all he's been on 18 months bereavement leave. They decide he'll also be 'on the road' covering Superman's soul search.
Superman does a few good deeds; with the past few years of cosmic level threats he hasn't really paid attention to the more 'mortal level' threats since he first put on the cape many years ago. He helps a messy diner clean up, kicks a drugs gang out of town, urges a sick man to seek medical attention and talks a woman down from a suicide drop.
Then, Superman leaves town for his next destination.
